` y application mea :une 11s,

. .The object `of my invention zis .to produce frommetallic parts which` may .be compactly packed for shipment andcreadily'fy assembled and erected by an average householdenan ornamental trellis. i f i The accompanying f drawings illustrate lmy invention. F-ig. 11is a perspective ofmy improved trellis partially assembled; Fig. 2

a kfragmentary view showing themanner of association of thejverticalfwiresand sup` porting cross bars; Fig. 3 ajfragmentary View showing the manner of association of the verticalL wires and thelower cross bar, Fig. 1 a perspective showing the parts packed for shipment; Fig. 5 a perspective- View of a modified form of lower cross bar, and Fig. 6 a perspective view of the Z bracket. f

In the drawings 10 indicates ya suitable4 jectible through a suitable perforation in one leg of the angle 10. The ends of the bars 12 are perforated with a suitable number of spaced perforations 15 through which may be projected the vertical wires 16. Said wires are most conveniently formed by doubling' a suitable length into yhairpin shape so as to form an eye 17 through which a fastening bolt 18 may be passed, said bolt also passing through a suitable perforation in the lower cross4 bar 19 secured by one of said bolts 18 to an arm of post 10. p

The arms of the hairpins 16-17 may be straight or kinked but, both for the erna@ mental effect and for the sake of strength I have found it desirable to form therein short kinks by heavy impact, such inanipuiation serving to very substantially stiffen the' wires and thus make possible the .use of a smaller sized wirethan ywould otherwise be practicable. n v p f Bars 12 and 19 and thewires 16-17 may be readily packed in the angle of the post 10 and held therein bybinding wires 2O as indicated in Fig. so that the partsmay'be shipped in a minimum space. y Any average house-holder may without difficulty assemble was.V sex-.iai ita-naam..

theparts as `showin .in l withthe aid 0f a screw driver ,and wrenc c Theshape of thecompletedfstructure may .bel verysnbstantially;varied.by ,varying the .length-s yof the various ycross bars and the 'distances betwe'en,`land `the arrangement of,

theperforations 15.v i 1 f y When the parts have been assembled as n shown in Fig.A 1 the lowerend of the post 510 may be readily driven into the ground by striking the upperend of the post` -f f especiallyin the lighter constructions This cross bar 19 is sheet metal with struck-up tongues 25 beneath which the wires 16-may be hooked and the tongues then bent down to retain the wires'in place. In order to place the trellis in position relative toa house or' porch, the upperend of bracket 10 is perforated at 30'so that itmay be secured f to ythe downwardly projecting arm 31-of a Z-bracket 32, theuuppe'r arm being readily attachable to the building. yIn case of needed height a length of angle iron similar c to post 10 may be driven into theground and post 10 secured thereto by means ofy bolts passed through perforationsl..

There is, of course,a decided objection 4to theutili'zation ofL an ordinary metallic support for growing plants because of the heat absorption and retention ofthe metal,

In my present construction this difiio'ulty` has been overcome.r First, because the cross bars, being perforated,` there is sufficient ycirculation of air'therethrough to keep thek temperature low andpsecond, byforming the wire 16 from a copper-bearing alloy, radiation is sutiiciently rapid to keep the temperature low.

i I claim as my invention:

l. A knock-down trellis comprising a v c post,`a plurality ofoross bars detaehably securedthereto at various pointsy in' its length, intermediateof its ends, said cross .bars being provided with a yplurality of spaced perforations, and a plurality of re`l' atively high `heat-radiant wires threaded through and retained Vin said perforations in such manner as to permit free air circulation through said perforations.

2. A knock-down trellis Comprising ,a

metallic angle post, a plurality of cross bars detachablysecured thereto at various points in its length, said cross bars being providedk with a plurality of spaced perforations, and

a plurality of Wiresthreaded through and retained in said perforations.

3. A knock-down trellis comprising a metallic angle post, a plurality of cross bars each having a middle portieri twisted into a plane at an angle to the plane of theends and the ends being perforated by a plurality of spaced perforations7 means by which `said cross bars may be detachably attached to the post, another cross bar Vand means Yfor detachably attaching said second-mentioned cross bar to the post, a plurality of Wires doubled upon themselves and of a size capable of projection through the perforations of the rst-mentionedcross bars, and means by which the said y Wires, at their point of doubling7 `may be detachably secured tothe second-mentioned cross bar.

4. A trellis comprising a post7 Va plurality of cross bars secured to said post at various points in its length intermediate of its ends and provided in their ends with a plurality yoit cross bars secured to said post at various points in itsvlength and providedin their ends with a plurality of spaced perforations, another cross bar secured t0 the post, a. plu`- rality of kin'ked Wires doubled upon themselves and their ends projected through the perforations of the first-mentioned cross A bars,v and means associated with the secondmentioned cross bar for retaining said Wires in place." l f lInvvitness whereof, I have hereunto vset my hand at La Fayette, Indiana, May, A. D. one thousand nine hundred and twenty-six. f
